Extending the Chemical Reach of the H3 Survey: Detailed Abundances of the Dwarf-galaxy Stellar Stream Wukong/LMS-1

Posted by August 25, 2023Chicago

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Guilherme Limberg, Alexander P. Ji, Rohan P. Naidu, Anirudh Chiti, Silvia Rossi | Summary: We present the first detailed chemical-abundance analysis of stars from the dwarf-galaxy stellar stream Wukong/LMS-1 covering a wide metallicity range ($-3.5 < rm[Fe/H] lesssim -1.3$). We find abundance patterns that are effectively […]

Including higher harmonics in gravitational-wave parameter estimation and cosmological implications for LISA

Posted by klaurent August 25, 2023September 7, 2023Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Yi Gong, Zhoujian Cao, Junjie Zhao, Lijing Shao, | Summary: Massive black holes (MBHs) are crucial in shaping their host galaxies. How the MBH co-evolves with its host galaxy is a pressing problem in astrophysics and cosmology. The valuable information carried by the binary MBH is encoded […]

Fully fluorinated non-carbon compounds NF3 and SF6 as ideal technosignature gases

Posted by klaurent August 25, 2023MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Janusz J. Petkowski, Jingcheng Huang, Zhuchang Zhan, Sai Ravela | Summary: Waste gas products from technological civilizations may accumulate in an exoplanet atmosphere to detectable levels. We propose nitrogen trifluoride (NF3) and sulfur hexafluoride (SF6) as ideal technosignature gases. Earth life avoids producing or using […]

Neutrino propagation through Earth: modeling uncertainties using nuPyProp

Posted by klaurent August 25, 2023September 7, 2023Chicago

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Diksha Garg, Mary Hall Reno, Sameer Patel, Alexander Ruestle, Yosui Akaike | Summary: Using the Earth as a neutrino converter, tau neutrino fluxes from astrophysical point sources can be detected by tau-lepton-induced extensive air showers (EASs). Both muon neutrino and tau neutrino induced upward-going EAS signals […]

Efficient Annotation for Medical Image Analysis: A One-Pass Selective Annotation Approach

Posted by klaurent August 25, 2023Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Yuli Wang, Peiyu Duan, Zhangxing Bian, Anqi Feng, Yuan Xue | Summary: Annotating biomedical images for supervised learning is a complex and labor-intensive task due to data diversity and its intricate nature. In this paper, we propose an innovative method, the efficient one-pass selective annotation (EPOSA), that […]

Enhancement of gravitational waves at Q-ball decay including non-linear density perturbations

Posted by dbos August 25, 2023Tokyo

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Kai Murai, , , | Summary: The existence of a stochastic gravitational wave background is indicated by the recent pulsar timing array (PTA) experiments. We study the enhanced production of second-order gravitational waves from the scalar perturbations when the universe experiences a transition from the […]
